The planting time of asparagus is knowledgeable, which month is the most suitable?

Today we are here to talk about the choice of planting time for asparagus. We all know that asparagus originates in the south, so it prefers a warm and humid environment. Generally speaking, if it is in the Yangtze River basin, it can grow between April and October.

But being able to grow is one thing, achieving the best output efficiency is another, how to choose the best planting time is still very fastidious.

First, the habits of asparagus

The scientific name of water spinach is water spinach, which is called differently in different regions. It is mainly called by Guizhou, Guangxi, Sichuan and other provinces, Guangdong is called Tongcai, Jiangsu is called rattan vegetable and so on.

Asparagus should grow in a warm and humid climate, fertile and moist soil, not cold-resistant, stems and leaves withered in case of frost. In the past, asparagus was rarely planted in the north, but with the development of greenhouse technology, it can now be planted in the north, as long as the appropriate soil, light, temperature and other conditions can be grasped.

Second, the choice of planting time of asparagus

1. Open-air planting

Planting asparagus in the open must be harvested before frost, because the cold tolerance of asparagus is not good, there will be a great loss if it can not be harvested in frost season, and it can be planted from April to July. The vitality of asparagus is relatively tenacious, and the requirements for soil conditions are not very strict. As long as it continues to water and fertilize during the growth period, it can grow rapidly.

two。 Greenhouse planting

Greenhouse planting can basically be produced every year, or it can be produced every year. In order to achieve high economic benefits, it should be planted from October to December and listed from December to March.

Matters needing attention in the process of planting asparagus

1. Soaking seeds in soil preparation: before planting asparagus, we must dig deep into the soil. Only by turning deep into the soil can the seeds of asparagus sprout better after planting. In addition to turning the land deeply, it is also necessary to apply fertilizer. each mu of land can be organic fertilizer, about 3000 grams, and about two kilograms of human and animal feces and urine, and then 100 kilograms of plant ash can be mixed into the soil. The seeds should be treated before sowing. You can soak the seeds in warm water for about 30 minutes, control the temperature of the water at about 60 degrees, pick them up after soaking in clean water for 24 hours, and put them into a temperature of about 25 degrees to accelerate germination. Humidity and temperature must be maintained during budding. After that, the seeds can be washed once a day. Can there be white spots on the seeds before they can be sown? The job of sprouting is very important, which determines whether it can grow healthily after sowing.

two。 Sowing: each plant can be 33 cm apart and covered with soil after sowing. At the same time, we can also use the method of sowing, but the sowing must be uniform in order to let the hollow vegetables grow evenly.

3. Field management: in addition to applying sufficient base fertilizer, it is also necessary to fertilize and water by stages after planting. Only in this way can higher output be achieved. During the seedling period, you can eat fertilizer, which is human urine for leaching, and the amount of fertilizer per mu should be about 1500 kg. When the seedlings grow to four leaves, you can use a mixture of 20 kg of compound fertilizer and 4 kg of urea. During the harvest period, about 8kg of compound fertilizer is used per mu of land. Asparagus needs a lot of water, so it should be watered in time to keep the soil moist after fertilization. Weeds should also be removed in time during the growth of asparagus. Because these weeds will absorb the nutrition of asparagus, timely removal can ensure that it can grow better.

4. Timely harvest: the last step is to wipe the hollow cabbage. About 45 days after the failure, the vegetables can be harvested appropriately, and during the harvest period, it can also be harvested according to its plant growth size, for example, when it is 30 centimeters high. But at this time, it is only suitable for continuous harvesting. If you live one-time, you can harvest it in the hollow cabbage, the plant is about 25 centimeters high, and Qixi Festival harvests. If it is harvested many times, the hollow cabbage plant should be left about ten centimeters at each harvest, so that it can continue to grow. We can also harvest asparagus regularly according to the sales volume of the market and the price of the market, which can not only ensure that we have the maximum income, but also improve our economic benefits in the central vegetable market.

Choosing a good planting time is very important, but field management is also important. Although the vitality of asparagus is relatively tenacious, but if you ignore the field management is also a risk of yield reduction, we must pay attention to it.
